Ott says they allow 300 people in every 15 minutes with a maximum capacity of 1,100.

While many people have used the aquarium's Facebook page to discuss their enjoyment of the new attraction, others are posting their disdain for the admission prices: $21.95 per adult or $15.95 for children ages 2-12. Annual passes are also available for $50 per adult, $90 per couple or $130 per family (two adults and two children). Parking is $3 Monday-Friday and $5 Saturday-Sunday.

In response to concerns regarding admission costs, Ott says their ticket structure came from researching other aquariums and comparing pricing.

"We are on the low end for aquariums," she explained in an e-mail.

The Greater Cleveland Aquarium is located in the FirstEnergy Powerhouse at 2000 Sycamore St.

It is open Monday-Sunday from 10 a.m. until 6 p.m. (last admission at 5 p.m.). It will take an estimated 90 minutes to make your way through the entire attraction.
